Can someone help on this? Somehow I blew the reflection of some lights and I'm not sure how to fix it.

This is earlier version of the picture:

This is the last version:

What can possibly make the light became square like that? There is objects in rectangle shape and emissive surfaces working as lights, I didn't change nothing there. It can be the asphalt surface? What kind of attribute make that?

The light source is outside the circle and 360 degrees. It's as if the curbing is the light source.All streetlight shadows are toward the center and the center has no shadow. Try reversing one or two streetlights and see if the shadow reverses. Look closely at the patch of light made by the streetlights outside the curbing (lower rendering)... To me it appears rectangular rather than spherical as it would occur naturally.

Remove the asphalt object (hide it) and create a primitive plane of the same size, and colored black. See if the problem persists on the created plane. If no, the issue is with the asphalt. If yes, it is with the light meshes (as I suspect).I don't know the light product but a quick search on the product page lets me see it uses geometric meshes. It looks to me that the settings for the light meshes aren't right.

If it doesn't work I suggest to use another lighting solution. Remove (hide) all the lights in the scene and try to create a simple mesh spotlight from one of the streetlamps. Have it be a Rectangle of 10X40, Render Emiter off, spotlight pointing down. That should isolate the problem.

I putted the new primitive and the same problem happened. I even create a new object UG Box Light Rim, to see if I had ruined any configuration, but had the same problem with the new created object.

What I can't understand is why the first picture was rounded. It is just like if some Daz version update changed the way this product interact with the scene.

I can go after another product but this is not good, any old scene can generate a new result, without me making any changes.

If the spotlight emitted a natural light, if you felt nothing seemed wrong with it, then the problem is with the Lights Setup product you used before. I would try to contact the content creator or ask around at DAZ forums about it.

It almost certainly won't be the lights added from UlatraGenessis Studio, as those consist of 'environments' (an HDRI) as well as having a range of mesh lights that show up as actual physical objects in the scene. It looks to be an issue with the actual street light objects. If you have done nothing too fancy with the items in the scene I'd suggest deleting the object and re-loading it.

This scene summarizes my tests:1. Create a primitive plane over the floor. Difuse color 105 105 1052. Removed the moon light from dome.3. Change the right back lamp for a spotligh using rectangle area, height 200, width 400, lumens 4000004. Removed the left back lamp and create a new "UG Box Light Rim": Same config from others On Surface: luminance to 40.000 On shaping: ScaleEmitter 34% Close top 50% Shallow flat 100% Shallow low 40% Straight sides -50%

If I was making the scene for first time, I would believe that this was the normal behavior but as I have the first picture rounded I'm breaking my head to understand how the light went square. Maybe something on render settings.

Still suspicious that some version change may have affected the product.

This scene is very small but I am using the same lamp post in several scenes

All the lighting except the top right is still rectangular. The top right is so dim or whatever it isn't even creating it's own shadow. I think if I were in charge of that scene, the center is far more important than the surrounding area... I would turn all the lighting 180° to highlight the center. Even installing lighting in the rafters of the center will not be properly lighted IMO.

I posted the problem on Daz's forum but as nobody answer it, I opened a Help Ticket today.

When they answer me I will post here

As floodlights illuminating the monument? It is a good suggestion, I am using only lampposts and the moon light in all segments to equalize them but this one can be done differently. Anyway I am locked trying find out what happened.
